Changing the Hydraulic
System Filter and Oil
The filter and oil are changed at the same time. Do Not reuse
oil. Once the new filter is installed and oil is added any air in
the system must be purged.
The bleeding process is repeated until the oil remains at the
FULL COLD line in the reservoir after purging. Failure to
properly perform this procedure can result in irreparable
damage to the transaxle drive system.

Removing Hydraulic System Filters
Important: When the hydraulic oil filter is removed, all
of the hydraulic oil in each transaxle will drain out. Use
a container that will handle 4.495 liters (152 oz) or larger.
1. Stop engine, wait for all moving parts to stop, and
allow engine to cool. Remove the key and engage the
parking brake.
2. Locate the filter and guards on each transaxle drive
system (Figure 59). Remove three screws securing the
filter guard and guard.

drains when the filter and vent plugs are removed.
5. Locate and remove the vent plug on each transmission
6. Unscrew the filter to remove and allow oil to drain
from the drive system.
